输出层偏导数：首先计算损失函数相对于输出层神经元输出的偏导数。这通常直接依赖于所选的损失函数。

While in the latter case, implementing a backport can be impractical compared to upgrading to the newest version of your application.
Backporting is every time a program patch or update is taken from a recent software Model and applied to an older Model of the exact same computer software.
was the final Formal release of Python two. So as to continue being latest with security patches and proceed experiencing all the new developments Python provides, organizations necessary to upgrade to Python 3 or start off freezing specifications and commit to legacy extensive-phrase aid.
In this state of affairs, the consumer is still working an more mature upstream Edition from the program with backport packages utilized. This doesn't give the total security features and great things about running the most recent Model from the software program. People should double-check to find out the particular program update number to make certain They're updating to the most recent Edition.
You can terminate at any time. The successful cancellation day will be for BackPR your forthcoming month; we simply cannot refund any credits for the current thirty day period.
Backporting calls for usage of the software package’s source code. As such, the backport is often created and supplied by the Main improvement crew for shut-supply software program.
Backporting is really a capture-all time period for any exercise that applies updates or patches from a more recent Model of program to an more mature Edition.
Backporting has quite a few rewards, however it really is in no way a straightforward resolve to complex safety problems. Further more, counting on a backport during the extended-expression might introduce other safety threats, the chance of which can outweigh that of the initial difficulty.
过程中，我们需要计算每个神经元函数对误差的导数，从而确定每个参数对误差的贡献，并利用梯度下降等优化

一章中的网络是能够学习的，但我们只将线性网络用于线性可分的类。 当然，我们想写通用的人工
根据问题的类型，输出层可以直接输出这些值（回归问题），或者通过激活函数（如softmax）转换为概率分布（分类问题）。
